Perhaps this is related to text size inflation/boosting? Steps to reproduce: 1. Open https://www.reddit.com/r/adviceanimals/.compact in Safari on iOS 9 (see screenshot) 2. Tap the title of one of the meme entries 3. If you are taken to a webpage instead of directly to an image file, start over and choose a different entry. 4. Tap the Back button or swipe back to navigate back to the subreddit homepage Expected result: The page should look basically the same as it did in Step 1. In particular, the text should be the same size. Actual result: The size of all of the page's text has been increased for no apparent reason. See screenshot.

Apparently this isn't image-specific. The same problem occurs when going to https://www.reddit.com/r/programming/comments/3mtzdq/git_260_released/cvi8b4m.compact , tapping the "Obligatory" link, and then going back.

Seems like we're triggering text-size-adjustment code now, and didn't before.

This appears to have been fixed in iOS 10.
